Preservation of "Atypical" Cosmetic Product Systems
By: John I. Yablonski and Sharon E. Mancuso, Bio-C…
The authors examine the facts that determine how to preserve and/or assess susceptibility/risk probabilities for cosmetic product systems that are "atypical" because they contain little or no water.

Measuring Synergy
By: David C. Steinberg, Steinberg & Associates
Because it is rare to find a single preservative that is broad spectrum enough to inhibit the different species of microbes, the synergistic use of multiple preservatives in cosmetics is useful.

New Liposome Gels by Self Organization of Vesicles and Intelligent Polymers
By: K.H. Diec, T. Sokolowski, K.P. Wittern and J. …
A new technique for forming liposome of lamellar gels calls for the build up of a nanoarchitecture of lipsomes (lamellar phases) crosslinked with hydrophobically modified water-soluble polymers (self assembly of vesicles and polymers).

Topically-Applied Soy Isoflavones Increase Skin Thickness
By: Schmid, D ;Zülli, F
The placebo-controlled study in humans has shown that soy isoflavones have a potent effect on the improvement of skin thickness in aged skin. The authors discuss the possible mechanisms of action.

Heat- and UV-Stable Cosmetic Enzymes from Deep Sea Bacteria
By: Claire mas-Chamberlin, Fracois Lamy, Philippe …
The use of protective enzymes in cosmetics has been resisted because of their well-known instability. However, we report here on heat- and UV-stable enzymes obtained from hydrothermal vents deep in the ocean.
